Quizplus · Accepted Answer

Moving average methods involve smoothing out fluctuations in a time series by taking an average of a subset of the data. This can help to reduce noise and make trends more easily visible. Exponential trend models also involve smoothing, but they are typically used to capture trends that change over time and are more sophisticated than simple moving averages. Polynomial trend models and autoregressive models are not smoothing techniques, but rather methods for modeling and predicting time series data.
